Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method of performing joint uplink processing by plural base stations, comprising: sending, by a serving base station, a request for uplink resources of a second base station for receiving uplink data of a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by the advance scheduler ahead of actual scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
A method for joint uplink processing by multiple base stations. A serving base station sends a request to a second base station for uplink resources. This request, generated by an "advance scheduler," asks the second base station to reserve resources for receiving uplink data from a mobile station. The "advance scheduler" makes scheduling decisions before the serving base station's "tactical scheduler." The serving base station receives first uplink data directly from the mobile station. It also receives second uplink data from the second base station, this data being what the second base station received from the mobile station using the requested uplink resources. The serving base station then combines the first and second data to get the final, accurate uplink data sent by the mobile station.
2. The method of claim 1 , wherein sending the request comprises sending the request to a tactical scheduler of the second base station to enable the second base station to schedule resources for uplink communications from the mobile station, wherein the scheduling of the resources by the second base station considers the uplink resources specified by the request.
The method of joint uplink processing where, when the serving base station sends a request to the second base station for uplink resources, the request goes to the second base station's "tactical scheduler." This enables the second base station to schedule its resources for uplink communication from the mobile station, with the scheduling considering the specific uplink resources that were requested by the serving base station. The serving base station sends a request to a second base station for uplink resources for receiving uplink data from a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by the advance scheduler ahead of actual scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
3. The method of claim 1 , further comprising: sending, by the serving base station, an uplink grant to the mobile station to assign uplink resources for the mobile station to send the first uplink data; and receiving, by the serving base station, the first uplink data on the uplink resources assigned by the uplink grant.
The joint uplink processing method where the serving base station sends an uplink grant to the mobile station. This grant assigns specific uplink resources that the mobile station should use to send its first uplink data to the serving base station. The serving base station then receives the first uplink data from the mobile station using the uplink resources specified in the uplink grant. The serving base station sends a request to a second base station for uplink resources for receiving uplink data from a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by the advance scheduler ahead of actual scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
4. The method of claim 3 , further comprising: sending, by the serving base station, a suspend indication in response to receiving the first uplink data; and after sending the suspend indication, sending, by the serving base station to the mobile station, a request for retransmission of the first uplink data if actual uplink data cannot be recovered from combining the first and second uplink data.
The joint uplink processing method involving a serving base station sending an uplink grant to a mobile station to assign uplink resources for the mobile station to send its first uplink data, and receiving the first uplink data on the assigned resources. The serving base station sends a "suspend indication" after receiving the first uplink data. After sending this indication, if the serving base station *cannot* recover the actual uplink data by combining the first and second uplink data (received from another base station), it sends the mobile station a request to retransmit the first uplink data. The serving base station sends a request to a second base station for uplink resources for receiving uplink data from a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by the advance scheduler ahead of actual scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
5. The method of claim 3 , further comprising: sending, by the serving base station, a suspend indication in response to receiving the first uplink data; and after sending the suspend indication, sending, by the serving base station, an uplink grant to the mobile station to enable the mobile station to transmit next uplink data, in response to the serving base station being able to successfully decode actual uplink data of the mobile station.
The joint uplink processing method involving a serving base station sending an uplink grant to a mobile station to assign uplink resources for the mobile station to send its first uplink data, and receiving the first uplink data on the assigned resources. The serving base station sends a "suspend indication" after receiving the first uplink data. After sending this indication, if the serving base station *can* successfully decode the actual uplink data, it sends another uplink grant to the mobile station. This new grant allows the mobile station to transmit the *next* uplink data. The serving base station sends a request to a second base station for uplink resources for receiving uplink data from a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by the advance scheduler ahead of actual scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
6. The method of claim 1 , further comprising: delaying, by the serving base station, provision of a hybrid ARQ (automatic repeat request) feedback from the serving base station to the mobile station until the serving base station is able to determine whether or not the second base station is able to cooperate with the serving base station to process the joint uplink data so that the serving base station can successfully decode the uplink data.
In this joint uplink processing method, the serving base station delays sending a hybrid ARQ (automatic repeat request) feedback to the mobile station. The delay happens until the serving base station can determine if the second base station will be able to cooperate in processing the joint uplink data. The serving base station needs this cooperation to successfully decode the uplink data. The serving base station sends a request to a second base station for uplink resources for receiving uplink data from a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by the advance scheduler ahead of actual scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
7. The method of claim 1 , further comprising: receiving, by the serving base station, a failure indication from the second base station, where the failure indication indicates that the second base station was unable to successfully decode the uplink data from the mobile station received by the second base station.
The joint uplink processing method where the serving base station receives a "failure indication" from the second base station. This indication signifies that the second base station could not successfully decode the uplink data it received from the mobile station. The serving base station sends a request to a second base station for uplink resources for receiving uplink data from a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by the advance scheduler ahead of actual scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
8. The method of claim 1 , wherein receiving the second uplink data by the serving base station from the second base station is an indication that the second base station was able to successfully decode the uplink data from the mobile station received by the second base station.
In this joint uplink processing method, when the serving base station receives the second uplink data from the second base station, this is interpreted as an indication that the second base station *was* able to successfully decode the uplink data received from the mobile station. The serving base station sends a request to a second base station for uplink resources for receiving uplink data from a mobile station, wherein sending the request is performed by an advance scheduler in the serving base station, the request being based on advance scheduling performed by a tactical scheduler in the serving base station; receiving, by the serving base station, first uplink data from the mobile station; receiving, by the serving base station from the second base station, second uplink data of the mobile station received by the second base station using the uplink resources specified by the request; and combining, by the serving base station, the first uplink data with the second uplink data received from the second base station to derive actual uplink data sent by the mobile station.
